Computer NetworksAn ISP is granted the block 80.70.56.0/21. The ISP needs to allocate addresses for 2 organizations each 500 addresses, 2 organizations each with 250 addresses and 3 organizations each with 50 addresses. Design a subnet and find the range of addresses and unallocated addresses for each organization.20237mComputer NetworksAn ISP is granted a block of addresses starting with 120.60.4.0/22. The ISP wants to distribute these blocks to 100 organizations with each organization receiving just eight addresses. Design the sub-blocks and give the slash notation for each sub-block. Find out how many addresses are still available after these allocations.20217mComputer NetworksWhat is the default subnet mask for a class A network?

PreviousConsider an instance of TCP's Additive Increase Multiplicative Decrease (AIMD) algorithm where the window size at the start of the slow start phase is 2 MSS and the threshold at the start of the first transmission is 8 MSS. Assume that a timeout occurs during the fifth transmission. Find the congestion window size at the end of the tenth transmission.NextAssume that source S and destination D are connected through two intermediate routers labelled R. Determine how many times each packet has to visit the network layer and the data link layer during a transmission from S to D.
